12. Sphenophorus lutulentus, sp. n. 



Oblong-oval, somewhat flattened above, opaque, nigro-piceous or black, the upper and under surfaces covered 

 with a pale brownish incrustation. Kostrum very stout, curved, compressed, about two-thirds tbe length 

 of the prothorax, sharply angulate at the apex beneath (as seen in profile), the broad basal portion closely 

 punctate and deeply sulcate, the apical portion smooth at the sides. Prothorax a little longer than 

 broad, somewhat rounded at the sides, abruptly constricted in front, feebly sinuate at the base, the apical 

 margin also sinuate on each side ; densely, coarsely, subconfluently punctate, excepb along the narrow, 

 abbreviated, smooth, raised median line. Scutellum narrow, bare. Elytra slightly wider than the 

 prothorax, rounded-subtriangular ; narrowly striate, the striae with small, widely scattered, rounded 

 punctures, the interstices flat, broad, each with one or two rows of minute punctures. Pygidium coarsely 

 punctate, closely ciliate at the apex in the tf , with a small tuft on each side at the tip in the $ . Beneath 

 and the legs somewhat closely punctate, the fifth ventral segment very coarsely punctured, unimpressed 

 in the <$ , the ventral excavation in this sex long and rather deep. Anterior and intermediate femora 

 and coxse each with a small tuft of hairs. Tibiae fringed with short hairs and sinuate within, the subapical 

 tooth short, the apical spur long. Third tarsal joint narrow.

the sculpture could scarcely be made out*. The chief 

 species are, the short, stout, compressed, apically angulate, basally 

 the coarsely, subconfluently punctured prothorax, with faintly 



indicated smooth median line and abrupt subapical constriction; and the finely 



subcordate 



The Texan 8. oblitus, Lee, is an allied form, with 



of the prothorax straighter behind, the tibiae armed with a long subapical tooth, &
